MTK移植camera说明
1、 裁剪模块

上面的修改是在平台没有默认AF（自动对焦）的功能（mtk6517和mtk6577\\mtk6572的平台没有默认AF功能），mtk6589的平台默认就支持AF功能。如果移植的摄像头没有AF功能就必须将默认的AF功能屏蔽掉（否则在DMA操作数据的时候很多的算法受影响，将在切换的时候很卡）！
在没有AF功能，就将全部设置成dummy_lens。ov8825af 指的是自动对焦功能。

2、 将custom/common/hal/imgsensor/中添加相应模块的hal层代码
在custom/common/kernel/imgsensor/中添加相应模块的Kernal层的代码 3、 SensorList[]的数据通过宏定义的判断，查看目前可能的摄像头的数量。同时框架层也是通过这个
变量来获取摄像头的数量。 custom/common/hal/imgsensor/src/sensorlist.cpp
·········································· MSDK_SENSOR_INIT_FUNCTION_STRUCT SensorList[] =

4、 custom/common/kernel/imgsensor/inc/kd_imgsensor.h定义设备ID，定义一个摄像头的
名字，这个名字对移植的成功与否问题不大 custom/common/kernel/imgsensor/inc/kd_imgsensor.h
······································· #define OV8830_SENSOR_ID 0x8830 #define OV9726_SENSOR_ID 0x9726 #define A5141MIPI_SENSOR_ID 0x4800 -

5、 为系统提供驱动调用的接口
其中必须注意上下的顺序必须一致！

6、 修改电源
参考datasheet上的时序。注意顺序，注意电源的大小，注意要关闭电源，注意时序。 7、 配置GPIO口
数据口和时钟口通常采用默认；
电源引脚在代码里面进行设置，不需要直接配置。 8、 9、
